A Solid State phono preamp sounds far better when left on all the time. On our Liberty B2B-1 I decided to put a power switch on the back of the unit should one decide to turn it off between listening sessions, it draws only about 25W when powered up. I recommend leaving it on 24/7 for best sound quality.
On our BIG Olympia Preamplifiers and Phono Stages there is no power switch they are designed to be left on 24/7.
In my own system I leave the front end's on 24/7 while turning of the power amps when not in use.
My favorite story on this subject was a gentleman from the San Francisco area whom bought a set of our Whitney amplifiers sometime in the late 90's. In 2008/9 he was visiting someone down here in San Diego and asked if he could bring them by for a check up. He brought them by on a Saturday and I gave them a check over and they measured / performed like the day they left our shop. The guy had never turned off these amps in 12 + years other than the occasional power outage.
Good Listening
